Progressive Insurance

It may seem like a recent comer to the American insurance market, but Progressive Insurance, known formally as Progressive Casualty Insurance Company, was actually established in 1927.

Known primarily for its aggressively priced auto insurance, Progressive actually offers home and renters insurance, commercial auto insurance, and an "other indemnities" segment which provides liability insurance (primarily for directors and officer) to small community banks, in addition to personal car insurance, as well as coverage for motorcycles, boats and recreational vehicles, both directly, and through partner companies.

Progressive is also the first major insurer in the U.S to offer pet injury insurance as an add-on to their auto coverage, though at present time this extends only to dogs and cars - the animals most likely to be in a car during an accident.

As of 2007, Progressive was ranked 159th on the Fortune 500 list, and was the third largest insurance company in the United States, behind Allstate and State Farm.
